mine went back for warranty replacement as the crank arm kept falling off.
I was polite but firm.
Alledgedly "manufacturing tolerance issue".
More like "rubbish design issue" IMO
It had a single pinchbolt and the new one that replaced it had a double pinchbolt (like XT)
Now I believe they use a system like Race Face.
BB seized too.

Sold replacement on eBay to a dutchman for more than I paid.
Went to Middleburn.

The pinch bolt came undone on mine (done up with allen key) surprisingly, after splashing £40 on a mini torque wrench and allen bits, nipping it up to 15Nm (think that's right) did the trick and it's not come lose since (didn't the STW review mention the bolt coming undone?).

I'll agree that it's a dodgy design, and the fitting instructions it came with didn't mention the torque value for the pinch bolt! Hopefully sorted with the new design.

Chainsuck? Mmm, I'd say no more than any other chainset I've used. I've had other SS chainrings - both middles and 3 ring sets which appear fine (and good vfm).

Bottom Brackets? Dogshite. Both the Aerozine and standard SS bb's suck in water and seize at the drop of a hat! Now happily running a HOPE bb instead.

Other than that I'd got one of the first sets for £99 which was cracking value, they look good and are nice and light, don't find them flexy but I'm not packing too many pies...

Pinch bolt came undone with mine and the 'knurling' on the inside of the crank arm became rounded off. I was told that they would not be warrantied as they had not been fitted properly, to the required torque settings. No instructions as to torque settings were included with the cranks.

I was also told that the BB that I had bought had been jet washed and this is why it had seized after 3 months. Several of the brake pads that I bought from them came away from the backing plate. I am an unhappy, and very firmly ex, customer.
